Abstract
The utility model discloses an unbonded back tension pre-stress stiffening core composite pile, which comprises an outer pile body, wherein a back tension unbonded pre-stress pile is arranged in the outer pile body and is used as a stiffening core pile. The unbonded back tension pre-stress stiffening core composite pile has the advantages that the structure is reasonable, the intensity of the pile body is high, and the foundation reinforcement treatment effect is good.
Description
Technical field
The utility model relates to the stake that a kind of Foundation Design is used.
Background technology
During existing ground is handled, used pile bodies such as composite pile, the pile foundation effect of its formation is not very good.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of the utility model is to provide, the no bonded post tensioning prestressing force strength core composite pile that the ground stabilization treatment effect is good.
The technical solution of the utility model is:
A kind of no bonded post tensioning prestressing force strength core composite pile is characterized in that: comprise outer pile body, the stake of posttension prestressing without bondn is set as the stake of strength core in the outer pile body.
Outer pile body is the stake of cement great soil group.
The stake of said posttension prestressing without bondn is preformed pile or present walling pile.
Be provided with steel strand in the stake of said posttension prestressing without bondn.
Outer pile body is stake, cement mixing pile or the rotary churning pile that slip casting forms.
The utility model is rational in infrastructure, and strength of the mixing pile is big, and the ground stabilization treatment effect is good.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the structural representation of an embodiment of the utility model.
The specific embodiment
A kind of no bonded post tensioning prestressing force strength core composite pile comprises outer pile body 1, the stake of posttension prestressing without bondn is set as strength core stake 2 in the outer pile body.Outer pile body is the stake of cement great soil group.Outer pile body is stake, cement mixing pile or the rotary churning pile that slip casting forms.The stake of said posttension prestressing without bondn is preformed pile or present walling pile.Be provided with steel strand 3 in the stake of said posttension prestressing without bondn.
During practical implementation, the outer pile body of can constructing earlier, the stake of back construction strength core, the strength core stake of also can constructing earlier, the outer pile body of back construction.
